CAN FOR POLISHING COMPOSITIONS.

Application filed January 24, 1907.

ToaZl whom it may concern:

Be it known that I, LoUIs M. KREGELIUS, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Cans for Polishing Compositions, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

The subject-matter of this application is an improved construction for cans designed to contain polishing compositions for coloring or bufling metal work and the like, keeping the same air tight while yet allowing the cake or mass of material to be readily removed when it is desired to use the same. Compounds or compositions of this character are usually put into the can, or container, designed for their reception, in a plastic condi-' tion and upon cooling many of them do not contract but on the contrary expand slightly so that it has been dillicult or impossible heretofore to Withdraw the cake of composition intact from the can.

The object of this my present invention is the provision of a can that may be readily opened in such fashion as to permit removal of the cake therefrom as a solid body.

To the accomplishment of this end said invention consists of means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain means embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing: Figure 1 represents, in its closed or sealed condition, a filled can, which can embodies the several improved features of my invention Fig. 2 represents the canes it appears upon the completion of the opening operation where such operation is accomplished by means of my improved features of construction; and Fig. 3 is a horizontal or transverse cross section of the can.

The object, which, as above stated, I herein seek to accomplish, it has heretofore been attempted to accomplish by providing means for slitting the can down one side, such means consisting in one form of can in an adaptation of a soldered can seam and the provision of means whereby the overlapping Specification of Letters Patent.

portions or edges of the can body forming such seam are stripped from each other. Another form is characterized by the provision of a wire secured to the bottom of the can and laterally disposed within the same whereby upon such cans end being removed the end of the wire is disclosed and when pulled will slit the can body lengthwise.

The objection to the first of the two methods just named of opening the can. resides in the fact that thereby only one side of the can is adapt-ed to be opened and this is not always sufficient to wholly release the contents therefrom, especially the lower portion of the cake. In other words it is desirable that the can be slit down at several points in order that the severed portions may be entirely opened away from such cake and the removal of the latter thus wholly unob- This result is obviously imp0ssible where the first form of can construction, just referred to, is employed; although to be sure, in. the second form it can be accomplished by the use of two or more wires for slitting the can. The provision of such extra wire, however, adds more or less to the expense of making the can since the insertion and securing of the wire in the can body preliminary to filling the same requires to be done manually.

In my present improved can structure I utilize a can body A of any approved form but most conveniently made cylindrical as shown. This cylindrical body portion of the can is formed out of a single rectangular sheet of the proper dimensions as is usual in the art of can making. However, in the course of such formation the sheet in question is given a fold a of the character illustrated in Fig. 3, such fold coming equidistantly between the ends of the sheet so as to be diametrically opposite the seam a wherewith such ends are subsequently joined together to form the completed can body. Such fold a being pressed, or laid, flat against the sheet provides a plurality of superimposed narrow strips of metal that constitute a wire-like element in the can wall just as do the overlapping thicknesses of metal entering into the seam proper. Inasmuch as for my purpose it is obviously a matter of indifference whether both these wire-elements be actual seams, or one be a seam and the other a fold of the character just described, I shall hereinafter refer by the term seam to either or both structures. Upon the cylinconcerns the operation. presently to be denot enter into this invention at all.

scribed. The remark just made concerning such longitudinal seam 0. applies with equal force to the seams a between the respective can ends A A and the can body as they do Near the upper end of longitudinal seam a and the opposite fold, or simulated seam, a in can body A is secured a clip (L or the like, that is adapted to receive the end of a key A of the type ordinarily employed in connection with preserve boxes and the like.

Having thus described the construction of my improved can, I will now proceed to explain t e manner in which such construction is utilized in my unique method for opening the same. The contents of the can, in the form of the cake B, are designed not quite to fill such can body, the upper end of the cake in the sealed can coming to within one-half inch or so of such cans top, as is represented by dotted line a, Fig. 1. To open the can, then, a can opener or other suitable tool is introduced just below can top A and a cut a completely encircling can, is effected so that such can top is entirely severed from the can body. In addition a slight starting out a is then made on either side of fold a and seam a. Key A is now taken and inserted in clip a which latter being located as before stated near the end of the seam or fold is laterally severed along with such seam end from the remainder of the can body. Accordingly, by rolling the key over and over downwardly along the' can side, the seam is rolled over upon itself and in this manner torn bodily from such can side, the latter being ripped down on both sides of the seam. The same operation is performed in connection with the simulated seam or fold a on the opposite side of the can. Thus it will be seen that the can body is severed into two semi-cylindrical portions which may be bent outwardly as shown in Fig. 2, leaving the cake entirely free as has heretofore been ex lained to be the object sought.

should state that the provision of clip a and the use of the particular type of key A illustrated in connection therewith is wholly optional with the manufacturer or user. Instead of employing the means shown for rolling or curling the seam or fold, over on itself a pair of pliers or any equivalent means may be employed with equally effective results. Thus certain kinds of can openers would be ada ted to be used as pliers for this pur ose so t at the same could be employed hot in cutting off the can top forming the slits a and thereupon rolling or curling down the same as described. It is not necessary, furthermore, that fold a be simulated, since, if desired to make the can body-out of more than a single sheet, there will obviously be a second seam necessitated in the course of its manufacture, which can be utilized in the same fashion as such simulated seam. Or in place of folding the sheet over upon itself it may be simply scored transversely and this scoring utilized in the same fashion as suchv fold or seam. The term simulated seam is intended to comprehend all these various forms which the extra seam has been described as being capable of assuming.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and dis tinctly claim as my invention:

1. In a new article of manufacture, a metallic can comprising a can body formed with a plurality of spaced longitudinal seams, each made up of overlapping thicknesses of metal ressed together so as to con- I stitute a wireike element in such body adapted to be torn therefrom, such body being thereby ripped down on both sides of said seam.

2. As a new article of manufacture, a

metallic can comprising a can body formed with a regular longitudinal seam and with a simulated seam substantially diametrically opposite said regular seam, each of said seams being. made up of overlapping thicknesses of, metal pressed together so as to constitute a wire-like element in such body adapted to be torn therefrom, such body being thereby ripped down on both sides of said seam.

3. In a can, the combination with a substantially cylindrical body portion comprising a plurality of spaced longitudinal seams, of means near the ends of said respective seams adapted to roll such seam over upon itself and thereby tear the same bodily from said body portion, the latter being ripped down on both sides of said fold or seam.

4. A container for a-substance of the character described, comprising a sealed metallic can body provided with a plurality of spaced longitudinal seams, and means adapted to rip said folds or seams respectively bodily from said can body, whereupon the severed ortions of the latter may be bent away from the contents.

5. A container for a substance of the character described, comprising a sealed substantially cylindrical metallic can body provided With a plurality of spaced longitudinal seams, and means near the upper ends of said respective seams adapted to roll such seam over upon itself and thereby tear the same bodily from said body, the latter being ripped down on both sides of said fold or seam.

6. A container for a substance of the character described, comprising a sealed, substantially cylindrical, can body provided with a lon itudinal fold or simulated seam substantially diametrically opposite the regular seam whereby the edges of the sheet forming such body are joined, the contents of said can filling the same partially only, whereby the top of said can may be removed by cutting round the top portion of said can body and means adapted to roll both such regular and simulated seams over upon themselves upon a starting slit being cut on each side thereof.
